I'm not sure I could turn the other cheek.
What an incredibly cruel thing to do.

I think I am with Jim on this one as considering it assault.  It is definitely something that needs to be reported to HR.   This is not a laughing matter or something that you can just apologize for.  I'm a dumper and I'm sure you know it can be worse.  Dry heaves, incredibly painful cramps, foamies, dizzy, cold sweats, racing heart...not something to play with. 

She wanted to see if you really got sick from sugar...that's sadistic.  *****  I don't know her and I want to smack her.    And then she is stupid enough to confess...and to you the victim!  Crazy.

I'm sorry this happened.  No one should do this to someone else.   

While everyone has good ideas.....How about making her some brownies....Isn't EX-LAX chocolate flavored?

 Gina1013, I like your style! I'm an eye-for-an-eye, paybacks-are-hell type of gal...

 I am so sorry.  That woman is sick.  I have an almond alergy.  If I eat an almond I run the risk of anaphalixis.  

Here is the email I would send her:

Dear Receptionist,

Thank you so much for thinking of the staff by bringing in that delicious chocolate truffle desert.   I was absolutely delighted to discover that you had even thought specifically of me when you told me it was sugar free.  Imagine my delight to find that I could finally participate with the entire office as I so often feel left out.

I know I have often talked about not being able to eat sugar because it would make me sick.  Here is what happens when I am exposed to sugar:

Symptoms  (http://www.mayoclinic.com/health/dumping-syndrome/DS00715/DSECTION=symptoms)

By Mayo Clinic staff

When symptoms of dumping syndrome occur during a meal or within 15 to 30 minutes following a meal, they may include:

• Nausea
• Vomiting
• Abdominal pain, cramps
• Diarrhea
• Dizziness, lightheadedness
• Bloating, belching
• Fatigue
• Heart palpitations, rapid heart rate

When signs and symptoms develop later, usually one to three hours after eating, they may include:

• Sweating
• Weakness, fatigue
• Dizziness, lightheadedness
• Shakiness
• Feelings of anxiety, nervousness
• Heart palpitations, rapid heart rate
• Fainting
• Mental confusion
• Diarrhea
• Low blood sugar (hypoglycemia)

Some people experience both early and late signs and symptoms. Conditions such as dizziness and heart palpitations can occur either early or late — or both. No matter when problems develop, however, they may be worse following a high-sugar meal, especially one that's rich in table sugar (sucrose) or fruit sugar (fructose).

Some people also experience low blood sugar (hypoglycemia), related to excessive levels of insulin delivered to the bloodstream as part of the syndrome. Hypoglycemia is more often related to late signs and symptoms. Insulin influences your tissues to take up the sugar present in your bloodstream.

There have even been cases where people have had to be taken to the hospital because of severe reactions and the effects related to insulin complications.

Imagine my suprise when I started to feel light headed and sick.  When my vision blurred and I felt faint.  Imagine my horror when you appologized for your experiment to see if sugar would truly make me sick.  

Your appology is insufficient because what you have done was to physically and emotionally assault me.  Your experiment could have sent me to the hospital to recieve emergency treatment at the expense of the company.  You did cost the office thirty minutes of down time where I should have been working but was physically unable to perform my job.  

Please note that this is also going to our supervisor.  

THAT is what I would do.  

I love your response.....we should print it out and carry it with us..

What a *****  I'd report her to your immediate supervisor, as this dumping may have been far more serious.  Be careful about "payback" as that may be detrimental to your empoyment.  DAVE

OMG! I'm in utter shock. There has been some good advice posted as to what you should/could do and I don't have anything more to add except, I'm sooo sorry that happened.

 I can't believe how horrible that is. You could have really had health problems. Would she have done this to a diabetic or someone who is allergic to peanuts? I agree that you should really report her even if she did apologize. I would be pissed.

Reading that made me furious!!!  She could have placed you in a medical emergency.  I do not dump, but I can have reactive hypoglycemic reactions to sugar....sometimes it can be on a small amount and it can be serious.  I have to agree with the first person *****sponded to your post.  I would report her.  HR needs to recognize this could have created a serious issue for you and was malicious.
